The booster boosts an input voltage to output a third voltage. The voltage detector detects at least one voltage level of the first to third voltages to output a selection signal. The selector transfers one of the first and second voltages as the input voltage of the booster in response to the selection signal. | 2011-03-03 |
20110050671 | NON-VOLATILE DISPLAY MODULE AND NON-VOLATILE DISPLAY APPARATUS - A non-volatile display module has a display panel and a driving circuit. The display panel has a substrate disposed with at least one scan line, at least one data line and at least one thin film transistor (TFT). The TFT is located at an interlaced area of the scan line and data line. The driving circuit has a memory unit, a voltage level generating unit and a voltage level selecting unit. The memory unit receives and stores at least one image control signal in accordance with a clock signal. The voltage level generating unit generates a plurality of voltage-level signals. The voltage level selecting unit is electrically connected with the scan line, the data line, the memory unit and the voltage level generating unit, and outputs one of the voltage-level signals to one scan line or one data line in accordance with the image control signal. A non-volatile display apparatus is also disclosed. | 2011-03-03 |
